Harry Styles’s face is in danger. Mark Wahlberg got wind of the fact that his daughters have caught a bad case of 1D fever and the famously tough action star (and father of four) just isn’t having it.

“The girls have turned to One Direction. My four-year old’s going ‘Daddy, I like Harry,’” Mark told late-night host Conan O’Brien. His two girls — Ella, 10, and Grace, who turns four tomorrow — are so gaga for the group, Dad’s getting a little jealous.

So how does Papa Bear Wahlberg — who, let’s be real, we wouldn’t want to meet in a dark alley — deal with his daughters’s pop star crushes? With his fists because Marky Mark.

“I’m like, ‘Well I’m gonna punch Harry in the nose when I see him,’” he joked (or at least, we think it was a joke).

“She pulls out pictures of him, and she’s hiding pictures in the room, and I pretend that I'm gonna rip them up and I get jealous,” Mark continues, “but if I see that little prick, he’s gonna get it. “

Mark even has a plan for how he’ll get revenge on the new men in his daughters’s lives. “I could say, ‘Hey I really wanna meet One Direction, I’m a big fan,’ and invite them to the [Transformers 4] premiere,” he said. “Maybe you can do the title track for the song, and then I would beat the crap out of them in a video.”

But in all seriousness, the protective father does want to pull some celebrity strings so his girls can meet their musical crushes. “That’ll be the only time I’ll ever introduce them to a boy,” he explains. “After that, they’re getting locked up. It’s Rapunzel time.”
